SPECIFICATION forming part of Letters Patent No. 419,683, dated January21, 1890.

Application filed February 20, 1889. erial No. 300,630. (No model.)

To aZZ whom it may concern:

Be it known that I,W1LLIAM M. Korrns, a citizen of the United States,and a resident of Orrville, county of \Vayne, State of Ohio, haveinvented a new and useful Improvement in Thrashing-Machines, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, making part of this specification.

My invention relates to improvements in thrashing-machines, moreparticularly to that class of machines known as vibrators; and itconsists in providing improved means of operating the several parts andto reduce the initial cost.

With these ends in view my invention consists in certain features ofconstruction and combination of parts, as hereinafter described, and setforth in the claims.

Figure 1 of the accompanying drawings is a view in perspective fromleft-hand front of a thrashing-machine, illustrating my invention; Fig.2, an elevation showing right-hand side; Fig. 3, an elevation showingleft-hand side; Fig. 4, a vertical longitudinal sectional view showingposition of parts; Fig. 5, aview in perspective of vibrator-supports;Fig. 6, a

7 .similar view of vibrator-hanger; Fig. 7, a plan from below, showingunder side of a portion of the machine; Fig. 8, a view comprising ahanger, vibrator-lever, and conneeting-link heads in perspective; Fig.9, a view from rear, showing the end of. the. machine.

Similar letters of reference indicate corresponding parts in all of thefigures of the drawings.

The frame of the machine is composed of stout horizontal sills A,vertical posts 13 B B and cross sills or girders O, the posts B and Bprojectedadistance below the sills A. The body portion of the machine isinclosed by sides and deck in the usual Way. The front end of said frameis secured to a bolster D, which rests upon an axle, as D, which issupported by carrying-wheels D The rear portion of the frame is securedto the axle D supported by carrying-wheels D The front portion of theframe is raised suflioiently high by the bolster D to allow the wheels Dto be turned under the body of the machine, and to secure the bolsterand machine in proper relation a reach, as D, is provided, having itsfront end secured to the bolster D andits rear end to a cross-girder D,secured to the lower portion of the posts B. A metal corner-plate D isprovided, which serves to inclose a portion of the front end of the bodyof the machine, as shown, and to form a portion of the end of thecylinder-casing, in which a bearing an is located, through which thecylindershaft extends, the said corner-plate resting on and secured tothat portion of the frame designated as A and B The thrashing-cylinder Emay be of any of theWell-known and approved forms. It is supported on anarm a, the rear end of which is secured to the frame-post B andextending forward and inwardly, the front end secured to the corner-ironor cylinder-casing, substantially as shown. The said arm is furthersupported by the post a, the upper end of which is bifurcated, theprongs a secured to the arm a, one on each side of the cylinder-shaft,as shown. The lower end of the post is secured to the frame-sill A. v

The winnowing-wheel 71 is supported in a U-shaped frame h and inclosedin the usual way. On the end of the Wheel-shaft is provided a pulleyadapted for a belt engagement with a driving-pulley, by which said wheelis rotated to produce the necessary blast to clean the thrashed grain.

It will be noticed that the thrashing-cylinder is shorter than the widthof the separator and is housed separately and outside of the body of themachine, by which arrangement the separating capacity is enlarged to apoint.

in excess of the thrashing capacity of the cylinder, thus assuring roomto spread out the thrashed straw, and by such means, as will behereinafter described, agitate the straw and cause the grain to falltherefrom to the graintable. In this case the vibrating table F iscomposed of a series of narrow troughs or tables F F having side boardsas},b, l 1aving serrated upper edges, and fins, as h, intermediate theirends, as shown, the bottom board of I) having perforations 11 throughwhich the thrashed grain may fall to the vibrating grain-table G. Thefront ends of the vibrators F are supported on an alternatelycrankedshaft H, the rear ends supported von.

links I. The said link is made ofcast metal in form substantially asthat shown in} Fig.

5, having two parallel pipe portions a in which pins of hard wood may beplaced from time to time, as occasion may require, to form the journals0..

The vibrating grain-table G is constructed as follows: The interveningspace between the side boards D is inclosed or covered a distance from wto so by overlapping bottom boards of", forming steps or offsets a, thatoperate to move the grain rearwardly as the table is vibrated. In therear portion of the bottom space, as froma: to 1 is placed a riddle a ofunusual length, in order to provide a large fiddling-surface to allow ofthe use of a smaller mesh than has been heretofore used in this positionand relation to a grain-table vibrated under a vibrating separator, andas it would be impractical to distribute or control the wind-blast fromthe ordinary windwheel used for such purposes over so large a surface asthat of the riddle a I place in the shoe Z a grain-board a upon whichthe grain that passes through the meshes of the front part of the riddlefrom m to will fall upon the board a the vibratory movement of whichwill cause the grain to move rearward to the end of the board a at whichpoint it will fall through the wind-blast from the winnowingwheel h tothe return-board a", thence down into the conveying-spout U out of themachine. A wind-board, as a, is placed in the shoe, standingtransversely to the direction of the wind, that may be turned to changethe direction or deflect a portion of the windblast, as may be desired.It will be noticed that the board a has a double purpose, that of agrain-board'over which the grain is conveyed; but it also forms'with thereturn-board a a throat or passage-way by which the blast of wind iscarried to a point central, or there-j about, to the riddle.

The grain-table G is supported on swinging hangers J, a stud-pin 11secured to the table, resting in the journal-box b in the lower portionof the swinging arm J. The upper portion of the arm is provided with aninwardly-projected portion, forming a journal,

as b, which rests in a journal-box, as 12, sup- 1 The lower portion of ithe arm J is provided with a square openended socket, which has anaperture, as 11 (see Fig. 6,) said aperture having fixed there- 1 in ablock of hard wood having a perforation corresponding with a similarperforation Z2 in the said socket portion of the hanger, the said blockforming the bearing for the studported on the sill A.

pin b*, on which the vibrating grain-table is supported. I prefer thisform and construction of journal-box, as in it is provided aninexpensive renewable journal-box formed of hard wood, which I havefound more desirable for'this service than metal. A worn-out block iseasily removed, a new one driven into the iron frame, ant thejournal-box formed by boring through the block with a proper-sizedboring-bit.

The cranked shaft 11 has mounted on its left-hand end a pulley K, tohave a belt engagement with a driving-pulley, as L, on thecylinder-shaft, and a pulley, as M, is also mounted on the shaft H. todrive other parts of the machine. 011 the right-hand end of shaft Hthere is mounted a crank-wheel P, to which one end of pitman Q ispivotally secured, as shown. The other end in a similar manner issecured to the upper portion of a vibrating lever B. Said lever ismounted 011 a cross-shaft S, supported in hanger, as (1, secured to theunder side of the main sills A, the said lever B extending a distancebelow the shaft S, as shown in Fig. 2. On the opposite end of said shaftis mounted a crosshead T. A link, as d, is provided, one end of which ispivotally secured to the upper portion of the cross-head T, the otherend to the side of the vibrator grain-table G, as shown at (Z Fig. 3,and a similar link d having one of its ends pivotally secured to thelower portion of the cross-head T and the other end to the side of ariddlesupporting shoe Z, as shown at (P, Fig. 3; and on the right-handside of the machine similar links d and d are provided, link (1 havingone end pivotally secured to the lever R at the point above therock-shaft S, the other end secured to the side of the grain-table G, asshown at (Z and link (1 having one end pivotally secured to the leverbelow the shaft S, the other end secured to the shoe Z, as shown at d,an aperture having been made through the side boards of the machine toallow the ends of the links d d to pass through for engagement with thegrain-board and shoe, as hereinafter stated.

The purpose and operation of the parts will be apparent. When thecylinder is in operation, motion will be communicated to shaft H, thecranked portions of which will give to the front ends of thevibrator-tables F alternately an upward and rearward, downward andforward, or rotary reciprocating movement, the rear ends of the tablesbeing supported on and vibrated over the links I. The crankwheel P,operating the pitmaniQ, will vibrate the lever B to rock the shaft S,which movement willvibrate the links cld in pairs, the upper links 61vibrating the grain-table G, the lower pair d vibrating the shoe Z. Thedriving centers may be varied, so as to give more or less throw to thevibrated parts of the machine. For instance, the distance of thecrank-pin on the wheel P may be placed at different points between theperiphery of the wheel and the shaft, or the other end of the pitman maybe placed nearer to or farther from the shaft S on the lever B and thelinks 61' d placed at such a distance from the shaft S as will give thedesired result. Preferably the links 1 are placed at a point nearer tothe shaft, as the shoe and riddles should not be vibrated so great adistance .as the grain-table G. It will be apparent that a machine thusconstructed may be operated with less power and be so adjusted as to runto vibrate the spouts longitudinally is pro-' yided, as shown in thedrawings, especially in Fig. 7, which consists of a sway-bar XV,pivotally secured to an arm G (projected from the rear bolster D at oneof its end portions, to which a crossbar is secured, forming arms d (Zprojecting at right angles to the bar NV. The grain-spout U is connectedwith the arm (1 by the link (i and the spout V to the arm d by the link(1 and to operate the sway-bar W a link, as Y, is provided, one end ofwhich is pivotally secured to the bar WV, the other end secured to thebottom of the shoe Z, the vibrations of which will carry the sway-bar WVforward and back, which movement will rotate the arms d (:1 about theirpivotal connection with the arm 0, by means of which the spouts arevibrated transversely to the movement of the grain table and shoe.

It will be noticed that all of the machinery connected with andincluding the vibrating portions of the machine are secured to andsupported on the heavy sills A. The advantage of this arrangement willbe apparent, as not only weight but whatever jar there may be caused bythe vibratory movements of the tables F and G and the shoe Z issustained by the sill A.

The tailings deposited by the spoutV into the elevator-trunk N arecarried up and forward to the cylinder in the usual way, and to preventthe cylinder throwing grain through the machine an apron, as O, issuspended from the deck, as shown in Fig. 4.
